Make sure to go through Bob Hasting's Search for the Zone webpage. There's stuff in there like the parallel universes and density shifting link which strongly spells out what's going on with Bob, DoppelArm and the Woodsmen (they can density shift at will from air spirit to "animal life"), reflections, timeshifting and also helps explain the function of the glass box device in NY.

You'll see that Cooper (density shifts) as he passes into into the glass box. The glass does a further shift on him. DoppelArm broke out of the box and tried to possess Sam and Tracey and ended up beating them to pieces at hyper speed because it wasn't properly density (and time) shifted into our reality.

The Robert A Heinlein links would be suggesting Heinlein's final Cat who walks through Walls novels. Dale Cooper is the Cat.

Heinrich Viegel is Bill Hastings doppelganger? If you are crossing into parallel realities chances are your doppelganger is close at hand like a reflection?

What's with the 25 year cycle for Cooper's release? Based on the density shift paper one has to multiply time up or down to correct. Either way when Laura said I'll see you in 25 years, that number is not random. It's tied to something.

"In physics, a wave packet (or wave train) is a short "burst" or "envelope" of localized wave action that travels as a unit"

Take Notice of the lines:
"Move along through time"
"Headed to a future"
"The great unknown"
"The train of life"

We ride this train
Always leaving something as we always move along
Move along through time *
All the headlights sees is darkness
In the great unknown
The great unknown

Heroes ride the train of life
Moving on in darkness leaving that once known
The horns blow out a warning
Headed to the future
The great unknown
The great unknown

This train stops for no one
Yet we're all aboard *
No soul knows where home is
'cept the one who knows the lord *****!!!
No soul knows where home is
'cept the one who knows the lord
(Now think : WE HAVE DESCENDED FROM PURE AIR")

I left my love behind us
In another time and place
Yet i'm sure to find it somewhere
When the big light sees your face
The train blows it's mournful tune
Darkness all around
All around

Always moving forward to that love unbound
The face of silence
Out in the great beyond
One day we'll be upon it
True love and grace be found
True love and grace be found

This train stops for no one
Yet we're all aboard
"No soul knows where home is
'cept the one who knows the lord"
No soul knows where home is
'cept the one who knows the lord

And... they are also labelled SPIKE TRAINS..

"In the context of spiking neural networks, the current activation level (modeled as some differential equation) is normally considered to be the neuron's state, with incoming spikes pushing this value higher, and then either firing or decaying over time. Various coding methods exist for interpreting the outgoing spike train as a real-value number, either relying on the frequency of spikes, or the timing between spikes, to encode information."

Those "trains"* are also known as..
Spikes, peaks, or even "BEATS"

As in BiNeural Beats:

"The Frequency following response (FFR), also referred to as Frequency Following Potential (FFP), is a specific response to hearing sound and music, by which neural oscillations adjust their frequency to match the rhythm of auditory stimuli. The use of sound with intent to influence cortical brainwave frequency is called auditory driving,[58][59] by which frequency of neural oscillation is 'driven' to entrain with that of the rhythm of a sound source."

Beat the beat going to school
Beat the beat going home
Beat the beat going to work
Beat the Beat going to sleep
Spaceman flying in my room **

Snowman riding on my broom
Got fear from ear to ear and all I see – is that impending doom
impending doom
Beat the beat going to school
Beat the beat going home
Beat the beat going to work
Beat the Beat going to sleep
So bring it on, you got the number –
you say you can so bring it on
So bring it on, you got the number –
Don’t like dancing on my own
So bring it on"

WOW BOB WOW!!!!
My head has been spinning since Sunday night. Still kinda is, but I'm good enough (I think ) to roll with this so....LETS ROCK.

Meanwhile....

- I knew we were in for it right away when the opening Rancho Rosa logo flashed the BLACK DOT. The one that appeared on Mr. Todd's screen. The one in native American is a symbol meaning DEATH.

- Frank tells Gordon about the missing pages from Laura's diary and the mention of two Coopers. Now things are getting somewhere.

- 1975, the first BLUE ROSE case, Lois Duffy and her doppleganger found by Gordon and Jeffries, watched the doppleganger return to the lodge after death, real Lois killed herself before standing trial for a murder she swore she didn't commit. Wow that was A LOT of information at once.....at least that's what I thought....until....

- HOLY FREAKING CRAAAAP!!! JANEY-E IS DIANE'S HALF-SISTER?!?!?!?

- Gordon's dream "We are like the dreamer who dreams and lives inside the dream. But who is the dreamer?" then he turns around and is reminded of the opening sequence in FWWM where Cooper tells him about a dream he's afraid of and Jeffries "shows up" and points at Cooper and says "who do you think that is right there?" to Gordon.

**note - we are now only 15 FREAKING MINUTES into the episode and I've already lost my mind. I was NOT prepared for what happened next....

- CHAD arrested!!! YAY!!!! He was such a nerfherder.

- (directly from my scribbles) HOLY.....JACK RABBITS PALACE!! Finally!! wait....that's NAIDO!!! (I thought for a split second it might be Josie)....2:53....PORTAL!!! OMG IT TOOK ANDY!!!!! Andy in White Lodge!!! THE GIANT.....no....THE FIREMAN!!!!! Andy is given a TESSERACT....shown a vision....MOTHER, mother and the vomiting of BOB, the Convenience Store, Gotta Light, Laura with two angels, a phone flashing, THE TWO COOPERS, him leading Lucy somewhere showing her something, THE LIGHTPOST (shown after Richard ran over the boy as well as right after Agt Desmond disappeared in FWWM).

- they reappear at Jack Rabbit's Palace and now ANDY IS THE MAN!!! Major props to Harry Goaz (Andy). He was pure of heart so he got to go to the Lodge and get the info they need.

- James is a security guard for the Great Northern Hotel. There's a point to this.....

- Freddie has been to the White Lodge via a portal in London, given the green gardening glove of the Iron Fist, and sent to Twin Peaks to "find his destiny". There's a point to this.....

- James hears the hum that Ben and Beverly heard, and it leads him to a door. THE POINT = James will discover the source of the hum, but it'll be behind a massive STONE WALL that Iron Fist Freddie will have to smash down to reveal what's causing the hum. What that will be, I have no clue. I was going to joke and say "The One Ring".

- SARAH FREAKING PALMER. OMG. Takes her face off like Laura did in the Lodge, only she's not Light. She has a left hand with the spirit mound blackened like the woodsmen and what has been confirmed to be Laura's smile. And then she bites dudes neck off.

- and two MORE new people in the booth at the Roadhouse, Megan and Sophie (from the credits). Though some good info in their conversation. Billy and Tina are indeed people in this timeline and this reality apparently, so it rules out a few theories about what's going on with Audrey.

YOU SEE WHY MY HEAD IS STILL SPINNING NOW???

I also saw a couple spikes stick out when she first takes off her face.

I am guessing she's possessed by Bob's mother, and the same being that murdered the young couple after exiting the glass box in N.Y.
